"I am very proud of the way the team has grown, this is a different feeling from nine months ago. This was an outstanding performance, but there is still a lot of work to do," said the coach.

"I am proud of our set piece and proud of the attack, but in particular the way we defended.

"The team plays for each other and that was shown in the defence tonight. They do it for each other. The system does not tackle, the players in the system needs to make the tackle. The reaction time of players, to get back on their feet and to get back in the position again, that was very rewarding to see."

But Coetzee will not let his side rest on their laurels as he targets a series whitewash in the third Test at Ellis Park next weekend.

He added: "Every test match is a must win for us. The series is won, but there is no relief. Every match is as important as the next. We will keep trying to improve."
